Part 2, Episode 08, Add a vaccination task

In this episode, I want to show you how to add a new task to the OCKDailyPageViewController. You should be familiar with this architecture by now but let’s take a deep look into it and use all of the knowledge that you got by now.

  static func makeVaccinationCheck() -> OCKTask {
    let schedule = OCKSchedule.dailyAtTime(
      hour: 0,
      minutes: 0,
      start: Date(),
      end: nil,
      text: nil,
      duration: .allDay)
    var task = OCKTask(
      id: TaskModel.vaccinationCheck.rawValue,
      title: "Vaccination Task",
      carePlanUUID: nil,
      schedule: schedule)
    task.instructions =
      "Please check your local health authorities for guidance and find out when you can get the vaccination."
    task.impactsAdherence = false
    return task
  }
    let taskList = [TaskManager.makeOnboarding(),
                    TaskManager.makeVaccinationCheck()]
static func vaccinationSurvey() -> ORKTask { 

}

    // The Welcome Instruction step.
    let welcomeInstructionStep = ORKInstructionStep(identifier: IdentifierModel.vaccinationWelcome.rawValue)
    welcomeInstructionStep.image = UIImage(named: "welcome-image")
    welcomeInstructionStep.imageContentMode = .scaleAspectFill
    welcomeInstructionStep.title = "Vaccination Survey!"
    welcomeInstructionStep.detailText = "Thank you for taking the Vaccination."

    // Birthday step
    let birthdayAnswerFormat = ORKAnswerFormat.dateAnswerFormat(
      withDefaultDate: nil,
      minimumDate: nil,
      maximumDate: Date(),
      calendar: nil)
    let birthdayStep = ORKQuestionStep(
      identifier: IdentifierModel.vaccinationBirthday.rawValue,
      title: "Step 1",
      question: "When is your birthday?",
      answer: birthdayAnswerFormat)
    birthdayStep.text = "This will help us to determin better overview based on your age."
    birthdayStep.isOptional = false
    // Vaccine Type step.
    let vaccineType = [
      ORKTextChoice(
        text: "Oxford–AstraZeneca",
        value: "Oxford–AstraZeneca" as NSCoding & NSCopying & NSObjectProtocol),

        withText: "Other",
        detailText: nil,
        value: "Other" as NSCoding & NSCopying & NSObjectProtocol,
        exclusive: true,
        textViewPlaceholderText: "enter additional information")
    ]

    let vaccineTypeAnswerFormat = ORKAnswerFormat.choiceAnswerFormat(with: .singleChoice, textChoices: vaccineType)
    let vaccineTypeStep = ORKQuestionStep(

    // Completion Step
    let completionStep = ORKCompletionStep(identifier: IdentifierModel.vaccinationCompletion.rawValue)
    completionStep.title = "Task Complete"
    completionStep.text =
      "Thank you for taking the Vaccince. Now you can see more details in the app as well as followup tasks."
    return ORKOrderedTask(
      identifier: IdentifierModel.vaccinationStep.rawValue,
      steps: [ welcomeInstructionStep, birthdayStep, vaccineTypeStep, dateStep, completionStep ])
  case vaccinationCheck
    case .vaccinationCheck:
